Not sure that this is a "travel product", but I'll take a stab anyway (moderator--feel free to move wherever you feel is appropriate).

Especially for business travelers out there, what do you carry with you as your emergency meal replacement in your briefcase (for when the flight/train that you just barely made plane sits on the tarmac for 2 hours sans service or for when your meeting runs late and room service will take an hour at 11:30 at night)? I keep a snickers with me, but it isn't particularly healthy (though it is filling), and I haven't waded through the meal/protein bars or granola that much. Anyone have any favorites that they'd recommend?

Thanks.
